Abstract (en)
[origin: US2014293924A1] Embodiments of the present invention provide a mapping method and apparatus for a search space of a physical downlink control channel. The method includes: determining a search space allocated to the PDCCH according to a resource allocation scheme; and mapping each of candidates of the PDCCH to a logic time frequency resource of the search space according to a predefined interval. With the method and apparatus of the embodiments of the present invention, a frequency selective scheduling gain is obtained by mapping different candidates onto discrete time frequency resources, or a frequency diversity gain is obtained by mapping one candidate onto discrete time frequency resources, thereby improving the performance of the PDCCH.
